If you wish to track the moon phases, there is a shareware program available called "Lunabar".  Click on the link above for more information.  The program puts an icon with the current moon phase in your task bar.  Clicking the icon in the taskbar brings up a whole wealth of information.  Unfortunately, they don't appear to be publishing the void-of-course tables in a timely fashion the way they used to.  I finally broke down and bought a good calendar...

*Update:  The Lunabar is now FREEWARE.  It still works the same way, but has been updated.  You can read all about it by clicking the link or picture above.

 

There is also a javacript display of the current Moon phase on our homepage at www.tarotforlife.com
